AirPlans eSIM Data Plans for South Korea

AirPlans does not provide a truly unlimited data eSIM for South Korea. All of the plans listed for South Korea have a hard data cap, such as 1 GB for the South Korea Unlimited 1 Day plan or 3 GB per day for the South Korea Unlimited 3‑ to 30‑day plans. When the data allowance is reached, the speed is reduced to a specified lower rate, for example 512 kbps or 1000 kbps, rather than remaining unlimited.

Travelers who need a larger, fixed amount of high‑speed data can choose from AirPlans’ fixed data plans. Examples include the South Korea 50GB 30‑day plan, which offers 50 GB of data for 30 days, and the South Korea 100GB 90‑day plan, which provides 100 GB for 90 days. These fixed data plans can be more cost‑effective for most users unless they anticipate extremely heavy data usage.

AirPlans does not provide any eSIM plans for South Korea that include a phone number or SMS capability. The available offerings are strictly data‑only plans, so travelers will not receive a local calling number from this provider.

If a traveler needs to make voice or text communications, they can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some network restrictions may affect these apps in South Korea, so it is advisable to confirm their availability before purchasing a plan.

AirPlans offers 21 single‑country plans and 46 multi‑country plans that include South Korea. The plans range in price from about $1.43 to $382.07 and provide data caps between 500 MB and 100 GB. Among the offerings, 33 plans feature a daily data cap while 34 provide a fixed data amount. Some plans allow tethering and offer reduced speeds of 512, 1000, 384, 1280, or 2050 kbps.
